Predictive Analytics for Excel

Video Description

In this easy-to-follow video course, learn how to forecast trended time series accurately in Excel: the foundation for a wide range of powerful predictive analytics applications!



Companies of all sizes are turning to exponential smoothing to accurately forecast trended data such as sales, demand, and other key business indicators. In this video course, world-class analytics expert Conrad Carlberg shows you how to use smoothing to forecast trends with a tool you already know: Microsoft Excel. Carlberg illuminates each technique through easy-to-follow video, with crystal-clear explanations reflecting his decades of experience solving complex analytical problems with Excel. You’ll learn how smoothing works and how to prepare data; quantify a forecast’s accuracy; use Excel Solver to reduce forecast error; interpret smoothing analyses; work with baselines; support your forecasts with regression analyses; diagnose trends using autocorrelation; detrend and forecast from a trended baseline; initialize forecast values; and backcast beyond the start of your baseline. You’ll learn hands-on through practice workbooks provided for your own use and adaptation. By the time you’re done, you’ll have mastered one of today’s most valuable predictive analytics skillsets—one you can use in nearly any field of business.
